Hi All,
I have equipment downtime data that is used to calculate Mean Time Between Failure and Mean Time To Repair. The fleet management system creates a new event frame every time a crew shift change occurs, thus splitting one long event into multiple shorter events. This skews the MTBF and MTTR data.
I need to calculate the start time of the next event that are of the same time code whi8le ingoring events with the same ending and starting time.
I have ranked the events according to Start Time and Equip ID and then calculated Next Start, but without looping through the data.

Next Start Calculated Column
This is one long event split into smaller segments:
@robertoosthuize , Based on what I got.
Next start date will be , a new column
minx(filter(Table, [ID_eqip] = earlier([ID_eqip]) && [Start_date] > earlier([Start Date])),[Start Date])
